Check the spectra to make sure that the strength of the signal is within 95 percent of maximum for the strongest peak. If the strongest peak in the spectra is more or less than full scale, adjust the attenuation to deliver the correct signal strength. Calibrate the IR spectrophotometer often....

How to interpret an IR spectrum and an FTIR spectrum FTIR spectra are information rich, but this very fact can make using and interpreting them challenging. A useful primer for interpreting FTIR can be foundhere. Even a simple, pure, single compound sample, like vani...
This lesson describes how to read and interpret proton NMR spectra of organic compounds, including peak splitting, the meaning of chemical shift due to deshielding, as well as peak integration. Related to this Question How many ^13 C signals would the following compound shown in a broad-band ...
Infrared energy has a longer wavelength than the visible spectrum. Explore how infrared spectroscopy (IR) is used to interpret infrared energy and create an identifiable spectrum and discover its applications in forensic science and homeland security. Related...
Photonics and artificial intelligence are enabling the creation of robots with new ways of interacting in business, medicine, imaging and many other applications. The robot age is upon us. The thought of robots might bring to mind helpful androids like C-3PO in “Star Wars” or Rosie from “...
have minimal TIR and still have significant decenter of the optical axis relative to the edge of the lens. In detail, the decentered asphere will impart some waviness to the TIR around the edge in this case, but it will often be much smaller than the tolerance and difficult to interpret. ...
1n,o). RSC and SWI/SNF are thus partially redundant and have different functions to remodel the promoter nucleosomes. To interpret the effect of RSC and SWI/SNF double depletion, we performed epistasis analysis on each dynamic parameter of transcription and called this method dynamic epistasis ...
To interpret our model, we further analyze the random forest regression results using SHAP (Shapley Additive exPlanations)35, a generalized metric for feature importance, which utilizes the game-theory-based Shapley values to calculate the contribution of each feature to the model’s output. SHAP in...
(Fig.2c), and comparing it to the corresponding evolution of PL peak position show, that early after dripping diethyl ether, the PL peak position is at a lower wavelength than the band edge (Supplementary Fig.3). We interpret this as the optical signature of a confinement effect, while ...
